From the rugged Scottish Highlands, Loch Duart has built an international reputation for truly exceptional tasting salmon through pioneering advances in animal husbandry and feed composition. From the French Laundry to the Royal Wedding, Loch Duart has graced the most discriminating tables in the world.
Can PCBs be removed from fish?
Based upon this analysis, it was concluded that cooking processes such as baking, broiling, microwave cooking, poaching, and roasting remove approximately 20 to 30% of the PCBs. Frying appears to remove more than 50%. PCB cooking losses also appears to be a function of the initial lipid concentration in the fish.
Is NZ farmed salmon toxic?
Toxic chemicals Currently, in New Zealand, feed for farmed salmon does not contain antibiotics, vaccines, steroids or colourants. Astaxanthin is naturally present in wild king salmon diets. It is included in fishfeed to mimic the diet of wild fish and is necessary for maintaining fish health.

Is Loch Duart salmon sustainable?
Loch Duart is sourcing their primary feed ingredient from a partner in Iceland that harvests wild capelin for their roe. This is an extremely sustainable source of marine proteins because capelin is a fast growing fish that is low on the trophic scale.
How long does it take PCBs to break down?
3.5 to 83 days
The time it takes for half of the amount of PCBs (initially) present to be broken down ranges from 3.5 to 83 days for molecules with 1 to 5 chlorine atoms. In water, PCBs are essentially broken down by the effect of sunlight (photolysis).
Is New Zealand salmon safe to eat raw?
A. Yes, although to have the best raw salmon experience we only recommend eating salmon that is within 3 days of the harvest date. For this reason, the best product for eating raw is a sashimi fillet as it is harvested to order the same day as it is dispatched.
Does NZ salmon have parasites?
Thankfully, it is incredibly rare to contract a parasitic infection from eating sushi or sashimi in Australia and New Zealand. There has been only one documented case of infection by a close relative of fish tapeworm (Pacific broad tapeworm), and one case of Anisakis infection in Australia.
What salmon should I not buy?
The Environmental Defense Fund lists farmed Atlantic salmon as an “Eco-Worst” choice and recommends people eat no more than 2 servings a month due to high PCB levels.
Which salmon should you not eat?
The Atlantic salmon and Pacific salmon sold throughout the United States were all once wild-caught. However, wild Atlantic salmon is now considered endangered because its population is declining. Catching wild Atlantic salmon is consequently banned.
What is Faroe Island salmon?
Faroese Salmon Renowned Around the World The surroundings in the Faroe Islands are the natural feeding ground of wild Atlantic Salmon. Wild salmon leave the rivers of Europe and travel to the feeding grounds around the islands. Here these wild salmon grow and thrive before heading back to the rivers of Europe to spawn.
Is Loch Duart salmon Wild?
Loch Duart Salmon are grown in the cold, clear waters of Northwest Scotland. This area was once home to some of the best Wild Atlantic Salmon runs in the world, but over fishing and other man-made issues, dating as far back as the 19th century, have made this wild fishery nearly non-existent.
Who owns salmon farms in Scotland?
Scottish Sea Farms – which is co-owned by Norwegian firms Leroy Seafood Group and SalMar – runs operations across mainland Scotland, Shetland and Orkney. It produced about 24,000 tonnes of Atlantic salmon in 2020.
What are the symptoms of PCB exposure?
Usually there are no immediate symptoms caused by exposure to PCBs, unless it is a massive exposure, such as falling in a tank containing PCBs or ingesting a significant amount of PCBs. In these cases, a worker may experience nausea, vomiting, respiratory irritation (sniffles, cough), and skin irritation (redness).
What health problems do PCBs cause?
PCBs are a probable human carcinogen. Studies of PCBs in humans have found increased rates of melanomas, liver cancer, gall bladder cancer, biliary tract cancer, gastrointestinal tract cancer, and brain cancer, and may be linked to breast cancer.
Does water dissolve PCBs?
Although PCBs prefer to bind to soil and other particles, small amounts will dissolve in water. Small concentrations of PCBs can also evaporate and be carried long distances in the air. Environmental Impacts: Fish and small organisms can absorb PCBs from the water and sediments in their habitat.
